html_radios is a custom function that creates html radio button group with provided data. It takes care of which item is selected by default as well. Required attributes are values and output, unless you use radios instead. All output is XHTML compatible.

Example 8-9. html_radios

index.php:



require('Smarty.php.class');

$smarty = new Smarty;

$smarty->assign('cust_ids', array(1000,1001,1002,1003));

$smarty->assign('cust_names', array('Joe Schmoe','Jack Smith','Jane

Johnson','Carlie Brown'));

$smarty->assign('customer_id', 1001);

$smarty->display('index.tpl');





index.tpl:



{html_radios values=$cust_ids checked=$customer_id output=$cust_names separator="<br />"}





index.php:



require('Smarty.php.class');

$smarty = new Smarty;

$smarty->assign('cust_radios', array(

			1001 => 'Joe Schmoe',

			1002 => 'Jack Smith',

			1003 => 'Jane Johnson',

			1004 => 'Charlie Brown'));

$smarty->assign('customer_id', 1001);

$smarty->display('index.tpl');





index.tpl:



{html_radios name="id" radios=$cust_radios checked=$customer_id separator="<br />"}





OUTPUT: (both examples)

<input type="radio" name="id[]" value="1001" checked="checked"><br />

<input type="radio" name="id[]" value="1002">Jane Johnson<br />

<input type="radio" name="id[]" value="1003">Charlie Brown<br />
